Quote:There would be a lot of trial and error in the design process, yes.
Mythbusters did an episode on the legend of the Han Dynasty Astronaut... that is, the tale of an astronomer who tried to reach the moon by, well, getting his servants to strap a crapload of rockets to a chair.
However, they had "man lifting" kites at the time and, despite frequent CATO problems, they had rockets capable of delivering a payload. The point being here is they had the basic tech available to build a glider with a primitive JATO engine.
Mind you I wouldn't want to be a test pilot back then.
CATO -- CAtastophe on Take Off. (it went BOOM)
JATO -- Jet Asisted Take Off. (A rocket booster for air craft)
